At the foot of the Nine Tribulations Cliff, Yun Ye's Taoist bones were gouged out by his junior brother Qi Jin. The cliff was stained with blood, and his soul was shattered into pieces like flying ashes. Five years later, Yun Ye returned to the fairy world with a broken body, but his boneless body wielded the Nine Netherworld Fire and changed his fate against the will of heaven. Qi Jin ascended to the position of Heavenly Lord and took charge of ten thousand sects, but he dreamed of those pupilless eyes every night - "You took my Taoist bones, but did you take my heart's blood?" He didn't know that Yun Ye was no longer the senior brother who was slaughtered by others, but a revengeful blade returning from the mountain of corpses and sea of blood. There is no benevolence in the immortal way, only blood debts can be repaid with blood.
